How fastis your line?
Two tests. Ookla for a fast headline; the Detailed test for bufferbloat + loss.
Click run, wait 20 seconds, see your download, upload, and ping. Works on Wi-Fi or wired. For absolute accuracy on the line itself, plug a laptop directly into the router via Ethernet first. If your numbers look low for the tier you're on, the help centre has the next-step checklist; if you're scoping an upgrade, compare the realistic speeds in the full fibre tiers we sell.
Powered by Ookla. The widget picks the closest available server on the Ookla network, which is usually but not always a UK one. Wired tests next to the router are more accurate than Wi-Fi tests from across the room — if the result looks low, plug a laptop into the router via Ethernet and re-run before raising a fault.
Runs in your browser against a separate global measurement network — different path to our own test up the page, so useful for confirming the bottleneck is your line, our network, or somewhere on the wider internet. Measures throughput, idle latency, jitter, latency under load (bufferbloat), packet loss, and rates real-world use cases (streaming / gaming / video calls). Takes about 30 seconds.
Tests. Different networks. Different things to learn.
The headline Ookla widget picks the closest available server on the Ookla network — best-case throughput. The Detailed test runs against a separate global measurement network and adds bufferbloat + packet-loss diagnostics, the numbers that actually predict video-call and gaming quality.
What 'good' looks like, by line type.
Rough guide for what to expect. Real-world delivered speed is usually 80–95% of advertised line rate on wired tests, lower on Wi-Fi depending on distance from the router.
| Line type | Expected download | Upload | Ping (UK) |
|---|---|---|---|
| FTTC 80 | 65–78 Mbps | 15–20 Mbps | 12–25 ms |
| FTTP 100/30 | 92–100 Mbps | 27–30 Mbps | 8–18 ms |
| FTTP 500/75 | 470–500 Mbps | 70–75 Mbps | 8–18 ms |
| FTTP 1000/115 | 920–1000 Mbps | 108–115 Mbps | 8–18 ms |
| Full fibre 1G symmetric | 950–1000 Mbps | 950–1000 Mbps | 8–18 ms |
| Leased line 1G symmetric | 1000 Mbps | 1000 Mbps | 5–12 ms |
Significantly below expected? Run a wired test (laptop direct into router via Ethernet) — if the wired number is also low, raise it as a fault. If only the Wi-Fi test is low, the issue is most likely Wi-Fi placement / interference, not the line.
This test for indicative. Other tools for diagnosis.
This test (fast, indicative)
20-second run against the nearest available Ookla server. Good enough for 'is my line broadly working at the right speed?' diagnostics.

Persistent low speed despite wired test? Open a ticket. We'll run line diagnostics from our end — sync rate, attenuation, error counts.
Common questions, answered.
Faster than this? Upgrade.
If your result is below what you expect, run a wired test, then open a ticket. If you want more, see what's available on your line.
